CCDs Fall to Less than 10 Percent of Image Sensor Market in 2010 as CMOS Surges
According to the market research firm iSuppli Corp., the light may be fading for Charge Coupled Device (CCD) image sensors as digital cameras, their principal application, switch to a less expensive and more efficient rival technology: the Complementary Metal Oxide Semiconductor (CMOS) sensor.
In the total market for image sensors—devices that convert an optical image into an electrical signal—the unit share of CCD sensors continues to decrease in 2010 compared to that of the competing CMOS technology.
Of the total 1.7 billion units forecasted for the image sensor market this year, CCDs will account for a roughly 9.8 percent share, down from 11.4 percent in 2009. And while the decrease in unit share is slight, the trend appears to be irreversible, with CCD sensors to make up only 4.7 percent of the market by 2014.
In contrast, the CMOS image sensor market will expand its unit share of the market to 90.2 percent this year, up from 88.6 percent in 2009. The increase is borne on the back of growing demand from equipment like cameras in mobile handsets, video conferencing and automotive driver-assist applications.
"While CCDs long had been thought of as a superior technology for image quality, CMOS technology has made great strides in recent years and narrowed the technology gap," said Pamela Tufegdzic, Analyst (Consumer Electronics) at iSuppli. "Furthermore, CMOS sensors use fewer components, consume less power and are cheaper to manufacture."
And although CMOS has been the mainstream technology for some time now in handsets and high-end digital cameras called DSLRs, CMOS penetration continues to increase in lower-end, point-and-shoot digital still cameras—a traditional CCD stronghold. As a sign of their growing usage, CMOS sensors are gaining traction in compact cameras and camcorders from brand-name manufacturers that used CCDs for those products in the past—industry stalwarts such as Canon Inc., Sony Corp., Samsung Electronics, Eastman Kodak Co., Casio Computer and JVC, iSuppli has determined.
The migration to CMOS from CCD will continue unabated for point-and-shoot cameras. By next year, the proportion of point-and-shoot models using CMOS will climb to 24 percent, up from 14 percent in 2009. The shift to CMOS among DSLR cameras is occurring even much faster: By 2014, fully 99 percent of DSLR models will be based on CMOS sensors.

.img, .ccd and .sub files?
i've downloaded a software from the internet. the package is inside a zip file. but when i opened the zip file, it only has files with .img, .ccd and .sub file extensions.
how can i use those files? what software must i use?
i think what you unzipped is a CD image, you'll either need to mount the image to a virtual drive or actually burn it to a cd/dvd, then you can install. below are the descriptions of those specific file extensions.
img: Many programs use this file extension for image data. The image may be a graphic or it may be an image of a disk (or disc). The graphic file will typically be smaller than a disk/disc image file.
ccd: Contains information about the logical structure of the CD. The .CCD file is an ASCII text file. It is used in conjunction with the .IMG and .SUB files of the same rootname. IsoBuster can interpret these files directly.
sub: SoftNI CaSat Suite is a multi-channel, multi-platform, modular subtitling solution for multilingual cable/satellite transmissions, providing subtitles in most European, Asian, African, and Middle Eastern languages.
